Single and dual digital interface


#1

What is the meaning of single digital interface and dual digital interface. and what is their difference?


#2

The connector has several wires in it and and communicate with the device that is plugged into it in several ways (UART, I2C, analog, digital). There is 2 digital wires as part of the 6 wires in the plug, devices may only need to use 1 of the 2 wires or some devices need to use both of the 2 digital wires.


#3

can you tell me why line follower sensor has dual digital interface while ultrasonic sensor has single digital interface. Is it because line follower has 2 sensor’s on it ? and I am new to the words UART and I2C can you explain.

Yes the line follower has 2 sensors and the ultra sonic senor only has 1 wire to operate the 1 senor
